Facebook App Allows You To Track The Flu Using Information From Your News Feed

Do you have the flu and wonder who gave it to you? Have you managed to stay healthy this season, but you're weary about who might make you sick? There's an app for that!

New social media apps may help you answer those questions. Facebook has an app that helps you sort through your friends to determine who to avoid and who is responsible for making you sick. The app says it checks your news feed for places that you've checked in and checks your friends' photos and status updates for sick symptoms.
